I have no idea who is calling me from this number.

Called and hung up

it's a scam - they call and ask for your credit card numbers.  Should be reported.

Just called and hung up..blocked the number

Called with a pre-recorded message regarding my credit card.  If you stay on the line long enough an actual "customer service rep" LOL will come on.  It sounds like a call center for telemarketers from a foreign country .  I didn't give any information but he wanted my cc #.   I worry about the older & younger people that might fall for this scam!
